Oh, I understand now, sorry. If I said "it makes no difference" then you'd ask what the heck I have f1 for in the first place...It actually doesn't make a difference. Maybe I should drop f1. f1 is an auto-increment int. so I imagine I'd want f1 re-incremented in numerical order to take the gaps out. Not exactly normalized (or normal:^), thanks.
